[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Example 1

[0034] Reference Figure 3 to Figure 11 , which is the first embodiment of the present invention, provides a roll material loading device for the production of nursing pants. The roll material loading device for the production of nursing pants includes a material storage component 200, a closing component 300 and a main body component 100. The three can cooperate to simultaneously perform conveying operations on multiple roll material nursing pants, which can eliminate intermittent pauses in single-roll conveying, thereby shortening the production cycle.

[0035] The material storage assembly 200 includes a material storage part 201, including a material storage box 201a, a rotating roller 201b, a guide plate 201c, a shielding door 201d and a handle 201e. The rotating roller 201b is located in the material storage box 201a, and the rotating roller 201b and the material storage box 201a are rotatably connected through a bearing. The guide plate 201c is fixed to the inner wall of the material storage box 201a, and the shielding door 201d is hinged to the top of the material storage box 201a. The handle 201e is fixed to one side of the rotating roller 201b, and the handle 201e is inserted into one side of the material storage box 201a. The handle 201e and the material storage box 201a are rotatably connected through a rotating shaft.

[0036] There are two guide plates 201c, both fixed to the inner wall of the storage box 201a. Five loading grooves corresponding to the nursing pants rolls are opened on the rotating roller 201b. When the rolls need to be transported, the shielding door 201d is moved to open the storage box 201a. At this time, the nursing pants rolls can be placed in the storage box 201a, and then the nursing pants rolls can be guided to the loading grooves on the rotating roller 201b by the guidance of the guide plate 201c. At this time, the rotating roller 201b can be rotated, and the rotating roller 201b can be rotated to guide the next roll to the loading groove. After the storage box 201a is filled, multiple rolls can be transported. The setting of the handle 201e is convenient for the user to rotate the rotating roller 201b.

[0037] The closing assembly 300 is arranged on the material storage box 201a, and includes a closing member 301, including a closing door 301a, a connecting frame 301b, a rack 301c, a gear 301d, a first spring 301e and a slide bar 301f. The connecting frame 301b is fixed to the bottom of the material storage box 201a, the closing door 301a is located in the connecting frame 301b, the closing door 301a and the connecting frame 301b are movably connected, the rack 301c is fixed to one side of the closing door 301a, the gear 301d is located on one side of the rack 301c, the gear 301d and the rack 301c are meshed, and the gear 301d is rotatably connected to one side of the connecting frame 301b through a rotating shaft, one end of the first spring 301e is fixed to one side of the rack 301c, and the other end is fixed to the inner wall of the connecting frame 301b, and the slide bar 301f is fixed to one side of the closing door 301a.

[0038] There are two closed doors 301a, both of which are arranged in the connecting frame 301b. The connecting frame 301b can support the closed door 301a to prevent the closed door 301a from deflecting. There are two racks 301c, both of which are fixed to one side of the closed door 301a. The first spring 301e and the slide bar 301f are respectively fixed to one side of the two closed doors 301a. When the coil needs to be unloaded, the slide bar 301f is moved, and the slide bar 301f can drive the closed door 301a to move when it moves. The movement of the closed door 301a can drive the rack 301c to move, and the movement of the rack 301c can drive the gear 301d to rotate. The rotation of the gear 301d can drive the other rack 301c to move, so that the two closed doors 301a can be opened towards each other at the same time, and then the coil on the rotating roller 201b can fall out of the storage box 201a. When the closed door 301a moves, a pulling force can be applied to the first spring 301e, and the rebound force of the first spring 301e can drive the closed door 301a to return to its original position.

[0039] Example 2

[0040] Reference Figure 3 Fig.11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] Specifically, the material storage assembly 200 also includes a limiting member 202, which is arranged on the shielding door 201d, and a first torsion spring 202a is fixed in the shielding door 201d, one end of the first torsion spring 202a is fixed in the material storage box 201a, a locking rod 202b is fixed on one side of the shielding door 201d, and a locking block 202c corresponding to the locking rod 202b is arranged on the top of the material storage box 201a.

[0042] When closing the shielding door 201d, a torsional force can be applied to the first torsion spring 202a. Then, in order to prevent the rotating force of the first torsion spring 202a from driving the shielding door 201d to open by itself, the shielding door 201d can be limited by engaging the locking rod 202b with the locking block 202c. The limiting of the shielding door 201d can be released by moving the locking block 202c to separate it from the locking rod 202b. Then, the rotating force of the first torsion spring 202a can drive the shielding door 201d to open.

[0043] Specifically, a support frame 202d is provided on the locking block 202c, the support frame 202d and the locking block 202c are hinged, a second torsion spring 202e is fixed to one side of the locking block 202c, the second torsion spring 202e is fixed to the inner wall of the support frame 202d, and a baffle 202f is fixed to one side of the support frame 202d.

[0044] When the locking block 202c is moved, a twisting force can be applied to the second torsion spring 202e. The locking block 202c moves and separates from the locking rod 202b, so that the limit on the shielding door 201d can be released. Then, the rotational force of the second torsion spring 202e can drive the locking block 202c to rotate back to its original position. The support frame 202d is fixed to the top of the storage box 201a. The locking block 202c can be supported by the setting of the support frame 202d to prevent the locking block 202c from shifting. The locking block 202c can be supported by the setting of the baffle 202f to prevent the locking block 202c from moving excessively and causing overturning.

[0045] Specifically, a cam 202g is sleeved on the outer side of the handle 201e, a limiting block 202h is set on one side of the cam 202g, a positioning ring 202i is sleeved on the outer side of the limiting block 202h, the limiting block 202h and the positioning ring 202i are movably connected, a second spring 202j is set in the limiting block 202h, and the positioning ring 202i is fixed to one side of the storage box 201a.

[0046] When the handle 201e is rotated, the cam 202g can be driven to rotate. When the cam 202g is rotated to contact the limit block 202h, it can be squeezed. At this time, a pulling force can be applied to the second spring 202j. When the cam 202g is rotated to separate from the limit block 202h, the rebound force of the second spring 202j can drive the limit block 202h to return to its original position. This reciprocating movement can have a damping effect when the handle 201e is rotated. When the user turns the handle 201e, the resistance change caused by the damping can be felt. This tactile feedback allows the user to intuitively understand the rotation status of the handle 201e.

[0047] Specifically, the closing component 300 also includes a rotating member 302, which is arranged on the slide bar 301f, and a sloped rod 302a is fixed to one side of the slide bar 301f, and an extrusion wheel 302b is arranged on one side of the sloped rod 302a. A rotating rod 302c is sleeved on the outer side of the extrusion wheel 302b, and the extrusion wheel 302b and the rotating rod 302c are rotatably connected through a bearing, and a rotating disk 302d is fixed to one end of the rotating rod 302c, and the rotating disk 302d is fixed to one side of the rotating roller 201b.

[0048] There are five rotating rods 302c, all of which are fixed to one side of the rotating disk 302d. There are five squeezing wheels 302b, all of which are hinged to one end of the rotating rod 302c. When the rotating roller 201b rotates, the rotating disk 302d can be driven to rotate. The rotation of the rotating disk 302d can drive the rotating rod 302c to rotate. The rotation of the rotating rod 302c can drive the squeezing wheel 302b to rotate. When the squeezing wheel 302b rotates to contact the inclined plane rod 302a, it can squeeze it, so that the inclined plane rod 302a can move. The movement of the inclined plane rod 302a can drive the sliding bar 301f to move. The movement of the sliding bar 301f can open the two closed doors 301a. When the squeezing wheel 302b rotates to separate from the inclined plane rod 302a, the inclined plane rod 302a can return to its original position for next use.

[0049] Specifically, a first pulley 302e is fixed to one side of the rotating disk 302d, a belt 302f is sleeved on the outer side of the first pulley 302e, and a second pulley 302g is arranged inside the belt 302f.

[0050] When the rotating disk 302d rotates, the first pulley 302e is driven to rotate, and the rotation of the first pulley 302e drives the belt 302f to rotate. The rotation of the belt 302f drives the second pulley 302g to rotate. When the rotating roller 201b rotates to the specified number of times, the limit on the shielding door 201d can be released to open it, and then the user can intuitively see the storage situation in the storage box 201a.

[0051] Example 3

[0052] Reference Figures 1 to 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0053] Specifically, a rotating wheel 302h is fixed on one side of the second pulley 302g, and the rotating wheel 302h is rotatably connected to one side of the material storage box 201a through a rotating shaft. A driving wheel 302i is provided on one side of the rotating wheel 302h, and the driving wheel 302i is fixed to one side of the locking block 202c.

[0054] A small number of teeth are provided on the rotating wheel 302h, and teeth are provided on one side of the driving wheel 302i. The rotating wheel 302h and the driving wheel 302i are meshed. When the second pulley 302g rotates, it will drive the rotating wheel 302h to rotate. When the rotating wheel 302h rotates to mesh with the teeth on the driving wheel 302i, the driving wheel 302i will rotate. At this time, the rotation of the driving wheel 302i can drive the locking block 202c to move. When the rotating wheel 302h rotates to separate from the driving wheel 302i, the locking block 202c can return to its original position.

[0055] Specifically, a protection frame 302j is fixed to one side of the material storage box 201a, and the protection frame 302j is sleeved on the outside of the inclined rod 302a. The protection frame 302j and the inclined rod 302a are movably connected.

[0056] The first pulley 302e and the second pulley 302g are both rotatably connected to the inner wall of the protection frame 302j via a rotating shaft. The protection frame 302j can support the first pulley 302e and the second pulley 302g to prevent them from deviating.

[0057] Specifically, it also includes a main body component 100, which is arranged on the material storage box 201a, including a coil elevator 101 and a support rod 102. The coil elevator 101 is fixed to one side of the material storage box 201a, and the support rod 102 is arranged on one side of the coil elevator 101.

[0058] A cylinder is provided on one side of the support rod 102, and a carrying frame is fixed on one side of the coil elevator 101. Before the coil falls, the cylinder can drive the support rod 102 to contract, and the coil can fall onto the carrying frame. Then, starting the cylinder can drive the support rod 102 to move, and the support rod 102 moves into the coil. At this time, starting the coil elevator 101 can lift the coil, and then moving the coil elevator 101 can move the coil to a specified position.

[0059] Specifically, a control panel 103 is fixed to one side of the coil elevator 101 .

[0060] The control panel 103 is used to control the start, stop and movement of the coil elevator 101. The operator can issue instructions through the buttons or knobs on the control panel 103 to let the coil elevator 101 start lifting the coil, and stop the operation of the coil elevator 101 after the coil reaches the specified position. When the coil needs to be moved horizontally to different processing equipment, the control panel 103 can also be used to control the movement direction and speed of the elevator. The control panel 103 can also be used to control the extension and retraction of the cylinder.

[0061] When in use, first place the nursing pants roll in the storage box 201a, and then guide the nursing pants roll to the bearing groove on the rotating roller 201b through the guidance of the guide plate 201c, and the excess roll will be stored in the storage box 201a, and then move the shielding door 201d to close it. When closing the shielding door 201d, a twisting force can be applied to the first torsion spring 202a, and then in order to prevent the rotation force of the first torsion spring 202a from driving the shielding door 201d to open by itself, the shielding door 201d can be limited by engaging the locking rod 202b with the locking block 202c. At this time, the roll elevator 101 can be moved to drive the roll to the specified position, and the handle 201e can be rotated after the roll elevator 101 is moved to the specified position.

[0062] The handle 201e can be rotated to drive the rotating roller 201b to rotate, and the cam 202g can be rotated when the handle 201e is rotated. When the cam 202g rotates and contacts the limit block 202h, it can be squeezed. At this time, a pulling force can be applied to the second spring 202j. When the cam 202g rotates to separate from the limit block 202h, the rebound force of the second spring 202j can drive the limit block 202h to return to its original position. This reciprocating motion can have a damping effect when the handle 201e is rotated. When the user rotates the handle 201e , and the resistance change caused by the damping can be felt. This tactile feedback allows the user to intuitively understand the rotation state of the handle 201e. When the roller 201b is rotated, the rotating disk 302d can be driven to rotate, and the rotation of the rotating disk 302d can drive the rotating rod 302c to rotate, and the rotation of the rotating rod 302c can drive the squeezing wheel 302b to rotate. When the squeezing wheel 302b rotates to contact the inclined rod 302a, it can squeeze it, so that the inclined rod 302a can move, and the movement of the inclined rod 302a can drive the slide bar 301f to move, and the slide bar 301f can move. 01f moves to open the two closed doors 301a. When the slide bar 301f moves, it can drive the closed door 301a to move. At this time, the movement of the closed door 301a can drive the rack 301c to move. The movement of the rack 301c will drive the gear 301d to rotate. The rotation of the gear 301d can drive another rack 301c to move. In this way, the two closed doors 301a can be opened towards each other at the same time. When the closed door 301a moves, it can apply a pulling force to the first spring 301e. At this time, when the bearing groove of the rotating roller 201b rotates to the bottom, the closed door 301a is closed. The door 301a can be opened, and then if there is a coil in the loading groove, it can fall into the loading frame. At this time, the rotating roller 201b continues to rotate to drive the extrusion wheel 302b to rotate and separate from the inclined rod 302a, and then the rebound force of the first spring 301e can drive the closed door 301a to close. After the coil falls into the loading frame, the support rod 102 is driven to move by starting the cylinder, and the support rod 102 moves into the coil. At this time, the coil lifting machine 101 can be started to lift the coil, and then the coil lifting machine 101 can be moved to move the coil to the specified position.

[0063] When the rotating disk 302d rotates, it drives the first pulley 302e to rotate. The first pulley 302e drives the belt 302f to rotate. The rotation of the belt 302f drives the second pulley 302g to rotate. When the second pulley 302g rotates, it drives the rotating wheel 302h to rotate. When the rotating wheel 302h rotates to mesh with the teeth on the driving wheel 302i, the driving wheel 302i rotates. At this time, the rotation of the driving wheel 302i can drive the locking block 20 2c moves, and when the locking block 202c is moved, a twisting force can be applied to the second torsion spring 202e. When the locking block 202c moves and separates from the locking rod 202b, the limit on the shielding door 201d can be released. Then, the rotating force of the first torsion spring 202a can drive the shielding door 201d to open automatically, so that the user can put the coil in. When the rotating wheel 302h rotates to separate from the driving wheel 302i, the locking block 202c will return to its original position through the rotating force of the second torsion spring 202e.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
